paper based SERS

#1

recently my project need to run a SERS simulation. My project is that I Grow AgNPs on cellulose paper substrate and then drop RhB on this substrate and do SERS. When I was using FDTD product, I found that it is hard for me to add a cellulose paper material to the material database. Would anyone mind telling me what I can do or share me your demo

Many thanks.

Hi,

Here is a knowledge base article on the different material models.

You can also find a link to a video on optical material modelling.

I found the following site which has information for the refractive index of cellulose:
http://refractiveindex.info/?shelf=3d&book=plastics&page=Cellulose

You could potentially add this as a sampled data type material which is shown in the link that @vivek provided above.
